Fe-P体系热力学再优化
Thermodynamic Reoptimization of the Fe-P System
摘要
Abstract
The Fe-P binary system was reoptimized by means of the CALPHAD approach.The Gibbs energy descriptions of every phase in the Fe-P binary system were optimized based on the latest experimental thermodynamic and phase diagram data.The solution phase (liquid,α-Fe,and γ-Fe) was described by the substitutional solution approximation and the other phases (Fe3P,Fe2P,FeP,FeP2,and FeP4) were treated as the stoichiometric compounds.The optimization was carried out using the Thermo-Calc(R) software package.The agreement of the optimized phase diagram and thermodynamic data with experimental results is good,and a self-consistent and reliable thermodynamic dataset is obtained to allow further optimization of Fe-based,P-containing multicomponent alloy systems.关键词
